Polyurethane foam is a solid polymeric foam based on polyurethane chemistry. As a specialist synthetic material with highly diverse applications, polyurethane foams are primarily used for thermal insulation and as a cushioning material in mattresses, upholstered furniture or as …

The term polyurethane is also called PU, Urethane, or Reflex foam. It covers a range of foams that are synthesized using polyol and isocyanate. It is an open-cell foam, generally of medium to low quality, with a shorter lifespan than other foams, but a wide variety of uses.

Flexible Polyurethane Foams are used mainly for assembly of doors and windows, infilling applications, sound and heat insulations, waterproof barriers and insulation against fire. Polyurethane Foam reacts rapidly with moisture in the air and expands after application.

Flexible polyurethane foam (FPF) is a polymer produced from the reaction of polyols and isocyanates, a chemical process pioneered in 1937. FPF is characterized by a cellular structure that allows for some degree of compression and resilience that provides a cushioning effect.

Polyurethane foam provides effective insulation against sound, heat, and water. Spraying polyurethane causes the foam to expand and fill the gaps. This creates a continuous insulation barrier that minimizes heat loss and prevents air infiltration.

Jan 29, 2025 · Flexibility: For delicate cushioning and adaptable shapes, PU foam’s open-cell foam is the ideal choice. Moisture Resistance: PE foam is the winner in environments requiring high moisture resistance or exposure to liquids.

What are the distinguishing characteristics of the new recyclable polyurethane V-Foam? BASF has worked with Vitra to develop a meltable polyurethane. After use, it can either be liquefied to make new PU foam or processed into granules for the production of injection-moulded components. That sounds very promising ...
